Demo will not play songs

[herbyb]

i uninstalled, found some problems, corrected them, reinstalled but it still doesn't work. here is what isee happening: the karaoke disc is read by the program, tracks and times are displayed but when i try to play a track the video screen opens and closes immediately;when i try to import tracks, the disc is read, the recording window opens and shows'initializing' then closes abrubtly and the track shows up on the list, but i know it was not recorded because i saw the way the audio cd worked and you could swee the transfer progress. the problem is probably in the cd device, i will wait until i have access to one i know works before i bother you again.
